These efforts will all be for naught, though, if Yahoo cannot make money off of it, and that means advertising. There is little that can make investors happier these days than to get mobile ads right, just ask Facebook.

That is why Yahoo has made yet another startup purchase, this time scooping up Distill, a provider of a video interviewing and scheduling service for recruiters. Distill broke the news in a blog post on its homepage on Thursday. No terms of the deal were disclosed.

Ok, so I can you all scratching your heads already, wondering why I went on about mobile advertising when Distill seems to have almost nothing to do with it. That is because the team over at Distill, who will now be working at Yahoo, was also the team behind mobile performance-based advertising platform Tapjoy. And that expertise is what they will be bringing to their new company.

"We’ll be drawing upon our expertise from the Tapjoy days to help build out Yahoo’s mobile advertising solutions," the Distill team said in the post.

"I can confirm that we are hiring seven employees from Distill, all of whom are expected to join Yahoo in Sunnyvale next week," a Yahoo spokesperson told VatorNews.

"Prior to creating Distill, this group was part of the original team behind the creation of Tapjoy, a mobile performance-based advertising platform that drove deep engagement and monetization opportunities for mobile app publishers. At Yahoo, they’ll be drawing upon their expertise from the Tapjoy days to help us build out our mobile advertising solutions."

The San Francisco-based Distill was a service that lets employers identifying the best candidates to interview, and eventually to hire, by allowing them to evaluate their problem-solving skills through a collaborative video interviewing platform.

The company raised $1.3 million in funding from Felicis Ventures, China’s Innovation Works and DN Capital in September.

Distill, of course, will be shutting down on March 30. Development of Distill Schedule and Distill Interview has already been stopped, and users will still be able to schedule interviews through the end of February.

Yahoo has good reason to want to bring on a team with experience in mobile advertising because the company is seeing tremendous growth in that sector.

“Our strategy is to proactively benefit from the platform shift to mobile,” Mayer said in an earnings call, noting that in 14 months, Yahoo added 150 million mobile users to hit a milestone of over 400 million mobile monthly users.
